' T0- all whom it may con/cern:

Be it known that I, EMILE RosENwALD: me-

v chanical builder, of Rue du Ponceau, inthe scription. This Inventlonrelates to the manufacture by mechanical means of buttons made ofvegetable ivory (corozo) or other materials capable of being worked in asimilar manner.

'The new method of manufacture consists in subjecting the pieces orblanks of corozo or other materialV to the successiye action of varioustools coacting to form the button in such manner-,that at every stepmade by the table o f the machine the various operations` refl quiredfor the manufacture of the button willl be simultaneously performed, theresult being that at each step made by the table a finished button willbe delivered from the machine, while there will always be a number of,buttons simultaneously in course of manufacture corresponding to thenumber of stages of the operation. According to this system are to beformed are placed in clips upon the machine-table, to which intermittentrotary motion is imparted, wherebyv each of the blanks is first broughtbeneath drilling-tools for forming any required number of holes in thebutton. In the machine represented in the accompanying drawings therearc two drills for piercingbuttons with two holes.

After having been drilled each blank' is brought `beneath a profiling orshaping tool and then over a finishing and separati-ng tool, whichcompletes and detaches the button. Atr each step of the machine therewill be two buttons being drilled, one being profiled and one beingIseparated,all the'tools operating simultaneously and a finished buttonbeing delivered at each movement of the table.

The accompanying drawings illustrate an example of the machinecomprising the combination of mechanism employed for the manufacture ofybuttons in the manner specified.

Figure l is a vertical ksection on line A B of Fig. 3. Fig. 2 is a partsectional elevaseriei No. 129,246. No medew tion of themachine lookingtoward the iinand '9 show details in side and facev views ofV themechanism for holding the table in the vvarious positions correspondingtothe diiferent stages of operation of the tools.

Figs. 10 and 1l show diagrammatic views of the different stages ofmanufacture of the buttons ings.

The same letters of reference denote like parts -in the several figures.r rlhe essential part of the machine is formed the table or ring a,receiving intermittent rotary motion and provided with spring-clips bfor clamping the blanks to be brought successively under the action ofthe several tools lof a hinged part b', which is turned downk when-it isnecessary to open the clips. the blanks of corozo from which thebuttonsI '1 When it is desired that each tool should produce one buttononly from each blank, the intermittent movement of the table would beregular, and this wouldbe more generally the case, although the machineshown is designed to. produce two buttons from the same blank,

in which case each angular movement of table a for bringing thedifferent blanks beneath each tool will be made up of two movementsviz.,a movement bringing beneath the tool the part of the blank from whichthe one button is to be produced. and a movement of ysmalleramplitudefor presenting to the tool that portion of the blank from whichthe second button is to be produced. Each tool thus performs twoconsecutive operations upon each blank at points corresponding to thedistance from center to center of the two buttons to be made from thesame blank. The sum of these two movements is equal to the pitch of theclips. I

The intermittent motion of table a is imparted by the followingarrangement: The table a carries an internal toothed ring a',

tooth air e, the pitch of the notches,-and consequently of the teeth,being alternately long and shortfsee Figs. 2, 7, 9) to correspond to thetwo movements which the table a is to receive. Beneath the ring c2 ismounted an escapement-detent g, pivoted upon an axis g', carried by theupper portion of a lever g2, pivoted upon a center g3, said lever beingheld in the position shown in Fig. 6, so as to present the detent g inthe path of tooth e5 by the action of one arm of an elbow-lever 7L,turning about a center t, Fig. l, whose other.

arm is jointed to a connecting-rod 7b2, connected to the pin ofvacrank-disk t, keyed onithe shaft of a worm-wheel 7a4, gearing with theworm f on main shaft f.

When one of the teeth t strikes against the detent g, the latter, whoseangular movement is limited, arrests the ring a?, and thereforeiablelrt, and thebelt d then slips upon the puley c Figs' and 7 inposition to present the notch e3, following the said tooth a5, in linewith a locking-detent gf, carried by lever g2. The lever on being drawnin the direction of the arrow, Fig. 8, by the crank its permitsdetentlever g2 under the action of its spring to engage its detent g* inthe notch af", Figs. 8 and 9. The ring e2 is thus held stationary duringthe whole time required for the tool to operate upon the part of theblank presented to it and which corresponds to the first button. By thisforward movement of the lever g2 the detent g escapes from the tooth eand is brought by its spring into the position shown in Fig. 9, so as tobe outY of the path of tooth 61,5, when by the backward movement oflever g2 ythe detent g is again brought into the path of the ring a2.

When the tools have completed their work, the lever /t again acts onlever g2, so as to disengage the detent gL from notch e3, whereupon thebelt drives the pulley c and table (t receives its second angularmovement limited by the engagement of detent g with the next followingtooth e, in which position the next notch a* registers with the detentg4, which enters it as before, so as to again hold the table stationaryduring the operation of the tools upon the portion of the blankcorrespending to the second button. When the operation is completed,detent g4 is withdrawn from notch a", and the table then receives suchan amount of angular movement as to ad- The detent g arrests the ringe2, as invancc each blank to the next following tool, said movementbeing limited by the next following tooth rzfr meeting the detent g, asbefore described.

The blanks are first drilled. ln themachine illustrated there are twodrills v7 j, Fig. 4, so mounted as to drill sin'lultaneously on each oftwo different blanks one of the two holes which each button should have.

The drills should be lowered into work and raised immediately afterwardto allow the feed movement of the table. To this end the twodrill-spindles are engaged by a cross-head on a lever-arm pivoted uponashaft lz, having a lever /ff connected by a link 1 with the pin of acrank-disk fz, fast on the shaft of a worm-wheel 71:, driven by worm 7on the main shaft f. In order to avoid breakage by excessive resistanceto the descent of' the drills, the lever is made in two parts hingedtogether at 71: and connected by a spring f7 as shown in Fig. 1.

Rotary motion' is imparted to the drills by belt-pulleys el j', whichwhile driving the drill-spindles allow of their vertical movement, thepulleys cf j" being driven by a belt ,Z from a pulley f2, fast on themain shaftf.

rlhe blank after being drilled is brought beneath the profiling orshaping'tool vny while fresh blanks are brought under the drills. Theprofiling-tool is also adapted to be brought down into work and to beraised again after performing its function, for which purpose itsspindle is engaged by the forked arm m of a lever pivoted at m2 andwhose other arm, ym3, is spring-jointed and coupled by a link m4 to thepin of a crank-disk fm, fast on the shaft of a worm-wheel fm in gearwith wormf. The tool is driven from a pulley f by a belt n on pulley n.,which allows the vertical movement of the tool-spindle. Upon thetool-spindle are also mounted blades m7, which by their rapid rotationdisperse the dust produced in the operation.

rlhe profiling-tool shapes the outline or profile of the button in thedifferent blanks as they are presented to it. The blanks having beenthus drilled and profiled are then presented to a final separating-toolo, by which the button is finished and detached. This tool, which isplaced below the table u, as shown in Fig. l, consists of a kind ofpunch having the profile which the button is to receive upon theopposite face to that produced by the preceding profiling-tool, saidtool also having both a vertical and rotary movement. The verticalmovement is regulated in such manner that the tool is brought into andout of work at the proper moments by a fork n', fast on the axis 71, ofthe elbow-lever, which controls the intermittent rotary motion of' table(t.

Rotary motion is imparted to the tool by means of a pulley 12, allowingof the vertical lOO TIO

Above the table in line with the tool o is, mounteda-receiving-tube p,Fig. 5, provided at its `lower end .with grippers p', said tubey beinglowered down onto the blank when the tool is raised into work, so as togrip the septo raise tube p to permit of table a being rotated forpresenting another button to the action of the stamping-tool the end of'arm p5 is forced backward by a toe p6 on a tripper-rod p7, actuated by acrank-disk p8, fast on the shaft of crank-disk h3, the free end of therod p7 being supported by a friction-roller QA When the rod p7 is at acertain inclination,

upon a spring p produces the sudden descent of thelreceiving-tube, andthe rod p7, passing below the horizontal in its backward movement,brings back the toe p into position to again act on arm p5 at the nextforward move- The driving-shaft may have a stopping and starting clutchr, controlled by a lever r', and the mainv shaft may be driven by abelt, as shown, from any suitable source of power. It should beunderstood 'that during every stoppage of the table ci the severalytools all act simultaneously, so that there will be always four blanksundergoing different stages of manufacture at the. same time, as shownin Fig.' 10, viz: first, drilling the left-hand hole;

l second, drilling the right-hand hole; third,

' button.

profiling; fourth, separation and expulsion of the button. Fig. 10 showsthese four operations as being performed simultaneously upon four blanksbrought opposite the different tools and presenting to the latter thepart of leach blank which corresponds to the left-hand Fig. 11 shows'these same four operations being `performed upon the same blanks afterthey have been shifted in'position beneath the tools for the purpose ofbringing under the action of the tools the parts cor- -responding. tothe right-hand buttons. The

lattendant has. only to place a blank in each of the clips in turn,while a finished button is delivered at each movement of the vtable fromthe moment when the first button has undergone an entire set ofoperations.A The same blank may be passed several times through themachine solong as sufficient material remains for making a button. Inthis case the The'buttons are successively,

attendant merelyT shifts the blank in the clip," Vso as to present afresh portion of the mate. rial to the action of the tools.

The buttons may be drilled with any number of holes, the drills beingarranged accordingly, and the machine may beadapted for making otherarticles, requiringv to undergo similar operations, besides buttons.

The number of tools employed" in combination with the'table o r ring maybe varied according to `the number of passes or phasesl needed for-making the button or other article, as well asY the kind of tools,according toY the nature of thearticle to be produced.

The forms, dimensions, details,and materials employed in theconstruction of the machine mayalso be varied without in any waychangling the nature of the invention.

I claim- 1. A machine for formingtwo buttons from d a single blank, said,machine comprising a circular table provided with clips for holding theblanksand receiving intermittent rotary mo ism arranged to operate insuch mannenthat the movements Vare ultimately long and short,

.the one movement having for effect to bring opposite each tool the partof the blank corresponding to the one button, and the other movementthe'` part of the blank correspond-` ing to the other button, 'the saidtable receiving its movement from a shaft which at same time operateseach of the tools, viz., the drills, the profilingand the finishingtool, which said IOO tools receive rotary motion and also a verticalmovement for the purpose of bringing them into operation and throwingthem out of Work at the proper moment to allow of the table being turnedto present the next blanks tothe tools.

2. In a machine of the kind specified, regulating the intermittentrotation of the table byv means of a spring-detent which successivelyengages the teeth of a ring carried by the ta-v ble, the pitch of saidteeth beingy alternately short and long to correspond respectively tothe long and short movements to be imparted to the table, the saiddetent being combined Withthe lever of another detent engaging innotches of similar pitch to the teeth, the de- IOS IIO

tents being so moved thatwhen the last-mentioned detent is engaged thetable is held stationary under the tools and the spring-detent isdisengaged, and conversely, by the movement in the opposite direction,the table is released to permit of its angular movement and bring thespring-detent into engagement with the next following tooth.

' 3. In a machine of the kind herein specified,

the receiving-tube disposed in alinement with the finishing andseparating tool, at the opposite side of the table, having grippers atthe lowerfend for seizing the button as it is detached and in which thebuttons successively detached rise and are finally delivered at theupper end of said tube as specified.

4. In a button-making machine, a table, means for alternately impartingrotary movements to the table at long and short distances, and drilling,shaping and finishing tools arranged over the table.

5. In a button-making machine, a table, means for imparting alternatelylong and short rotary movements to the table, a plurality of' drillsover the table, a shaping-tool, a finishing-tool arranged below thetable, a receivingtube above the table in line with said finishing-tool,and blank-holding,` devices on thc table.
